Helly Hansen JR Lifa Merino Midweight children's thermal underwear set black (49403_991)

Children's Helly Hansen JR Lifa Merino Midweight black thermal underwear set is technologically advanced clothing designed with comfort and functionality in mind for various weather conditions. The main feature of this underwear is the use of high-quality materials such as merino wool and polypropylene. Thanks to this combination, the set offers optimal thermal insulation and breathability, which is crucial during intense physical activity.

Material

Merino wool is known for its thermoregulatory properties, keeping warmth even in damp conditions. Polypropylene adds lightness and increases the durability of the entire construction, as well as supports quick sweat evaporation from the skin surface.

Fit and Construction

The Helly Hansen JR Lifa Merino Midweight black thermal underwear set features a regular fit that ensures comfort and freedom of movement. Long legs and sleeves provide additional protection against the cold, which is especially important on cooler days. The round neckline adds a classic look while ensuring a comfortable fit.

Technologies and Functionality

The use of LIFA® technology combined with Merino Wool makes the underwear not only warm but also exceptionally breathable. LIFA® is responsible for effective moisture wicking, helping to keep the skin dry even during increased physical activity. This makes the set ideal for children who actively spend time outdoors.

Care Instructions

To ensure longevity and maintain the properties of the underwear, it is recommended to avoid using fabric softeners during washing. This will preserve the full functionality of the materials responsible for thermoregulation and breathability. The set weighs 250 g, making it lightweight and easy to store and transport.

LIFA®
A technology based on a special fibre construction that is responsible for thermal insulation and moisture wicking. It consists of an inner hydrophobic layer and another layer, the hydrophilic layer. The hydrophobic properties mean that the material does not absorb perspiration, but carries it away to the hydrophilic layer, where the perspiration is absorbed. The very lightweight LIFA® fibres are ideal for thermoactive clothing.
Merino Wool
Using the properties of Merino wool, combined with KASK's exclusive helmet technology, the inner liner provides comfort without precedent. The natural fibres of Merino wool, when in contact with the skin, regulate body temperature, guarantee excellent air permeability and speed drying.
